Description

PRIORITY DATA
This application claims priority of Chinese patent application number 200610023308.3, filed Jan. 12, 2006, the disclosure of which is incorporated herein by reference.
TECHNOLOGICAL FIELD
The present invention generally relates to a Chinese medicinal composition for treat, preventing or ameliorating a liver disease.
BACKGROUND OF THE INVENTION
Liver fibrosis is a pathological process through which chronic liver disease such as chronic hepatitis B, alcoholic liver disease, fatty liver etc. developed into liver cirrhosis. The formation and development of liver fibrosis crucially affect prognosis and outcome of chronic liver diseases, and treatment of liver fibrosis is the one of the two most challenging tasks in the clinical treatment of chronic liver diseases, the other being etiologic treatment. The statistics data shown that there are 1.5 billion hepatitis B infectors in our country, among which there are thirty million patients suffering from chronic hepatitis Bs. The hazard of chronic hepatitis is well documented, which could infect other people on one hand, on the other it could develop into liver fibrosis.
It is observed that 65 wt % of patients with slight hepatitis B have liver fibrosis, but 100 wt % in moderate and severe patients. Over 30 wt % of chronic hepatitis patients will inevitably develop into liver cirrhosis. Nowadays in China, more than 10 wt % of population suffers from fatty liver, in which 50 wt % patients are due to obesity and 57.5 wt % due to alcohol. In addition the incidence of alcoholic liver diseases will increase as the living standard improves. No matter alcoholic or non alcoholic fatty liver diseases, the incidence of liver fibrosis has reached 25 wt % of patient population, 1.5 wt %˜8 wt % of which will become liver cirrhosis.
Liver fibrosis is a active repairing reaction to chronic damage, which characters with extracellular matrix (ECM) overproduction and deposition and the morphological features of hepatic sinusoid capillarization and lobule fibrosis. Almost all the chronic liver diseases, including chronic hepatitis B and C, chronic schistosomiasis, chronic alcoholic and drug damage, autoimmunity liver diseases have the pathological feature of liver fibrosis. These diseases would develop into liver fibrosis as the fibrosis continues, accompanying by liver dysfunction and portal hypertension, which severely affect patients' health and threaten their life at last.
Modern medicine researches indicated that hepatic stellate cell activation is the cellular basis of liver fibrogenesis, while imbalance of ECM metabolism including collagens that character as its production exceeding degradation is the biochemical foundation of fibrosis. It is now recognized that liver fibrosis is reversible, and, to some degree, liver cirrhosis can also be reversed. Therefore anti-fibrosis treatment is not only important but feasible and of clinical significance.
An existent technology, which is a capsule preparation (China patent: 99113887.2), made from salvia miltiorrhiza, pruni persicae, cordyceps mycelial threads and so on, can be effective against liver fibrosis due to chronic hepatitis B. However, this preparation has some shortcomings, including the shortcomings in dosage, moisture absorption, stimulation to stomach and intestine and etc. And these drawbacks would affect the preparation's stability and pharmacodynamic function.

Example 8 Pharmacological Action Experiment
(1) Prophylaxis Action on Liver Fibrosis
Pharmacological model: The liver fibrosis model in rat was induced by hypodermical injection of CCl4 and fed with the food containing high lipid and low protein. 100 wt % CCl4 was used at the first injection with a dosage of 1 ml/kg wt rat, then 40 wt % CCl4 in olive oil with a dosage of 3 ml/kg wt. was applied, twice per week and lasting for 2 weeks. During the first 2 weeks of intoxication, the rats were fed with the food containing 79.5 wt % maizena, 20 wt % grease and 0.5 wt % cholesterol, then with the pure maize food for later 4 weeks.
Models grouping and drug administration: the model rats were divided into model control, Fuzhenghuayu Prep I, Recipe Fuzhenghuayu Prep II and Vitamin E group, while the normal rats were normal control, with total 5 groups. Fuzhenghuayu Prep I and II group orally took with Fuzhenghuayu Prep I and II respectively at the dose of 4.6 g/kg, Vitamin E group received 50 mg/kg of VitE, The drugs were administrated once every day for 6 weeks. All dosages were 10 times human dosage with 65 kg by the same body weight.
Pharmacodynamic function: The liver tissue pathological examination show Fuzhenghuayu Prep I, Fuzhenghuayu Prep II could obviously attenuate hepatic inflammation and collagen deposition in the fibrotic model rat livers. According to well recognized standards of grading and staging for evaluation of liver inflammation and fibrosis, we found that all above 3 drugs could decrease liver fibrosis staging score, and Fuzhenghuayu Prep I had the best action among them. FIG. 1 showed the effect of different Fuzhenghuayu Preps on rat liver fibrosis stages induced by CCl4.
Serum and liver tissue biochemical examinations showed that Fuzhenghuayu Prep I and Fuzhenghuayu Prep II could improve the serum liver function parameters obviously in model rats, decreased hepatic collagen level (Hyp content), and decreased the contents of triglyceride (TG) and malondialdehyde (MDA), superoxide dismutase (SOD) activity significantly. There are no obvious difference between Fuzhenghuayu Preps and VitE. These indicated that both Fuzhenghuayu Prep I and II have good actions against liver fibrosis and lipid peroxidation. Compared to Fuzhenghuayu Prep II, Fuzhenghuayu Prep I have a better effect on lowering ALT level, hepatic collagen content, TAG and MDA content. Table 2 expressed the effect of different Fuzhenghuayu Preps on the serum liver function parameters in fibrotic rats induced by CCl4. Table 3 expressed the effect of different Fuzhenghuayu Preps on hepatic Hyp, TAG, MAD contents and SOD activity in fibrotic rats induced by CCl4 (x±s).

(2) The Treatment Effect of Fuzheng Huayu Preps on the Hepatic Fibrosis in Rats Induced by (Dimethylnitrosamine, DMN).
Pharmacological model: The hepatic fibrosis model was induced by intraperitoneal injections of dimethylnitrosamine at a dosage of 1 μg/kg rat wt, the injection was given on the first consecutive 3 days of each week over a period of 4 weeks, once per day.
Groups and drug administration: After establishing the model, the model rats were divided into model control, Fuzheng Huayu Prep I, Fuzheng Huayu Prep II, and (N-Acetylcysteine, NAC) groups, also normal rats was set as the normal control, with total 5 groups. The model rats in Fuzheng Huayu Prep I and II took orally Fuzheng Huayu decoction at the dosage of 4.6 g/kg rat wt from the beginning of the 5th week to end of the 8th week, one time per day for 4 weeks, NAC group received NAC at the dosage of 100 mg/kg wt, and controls took the same volume of saline. (body weight equivalent to 10 times of 65 kg adult dosage).
Pharmacodynamic effect: After the treatment of Fuzheng Huayu prep I and II, the histological pathological examination showed that the inflammation and collagen deposition alleviated obviously in model rats, and the hepatic fibrosis staging obviously decreased. There were no significant difference between Fuzheng Huayu Preps and NAC treated groups. However, Fuzheng Huayu Prep I group had better action than group II.
FIG. 4 shows the different influence of hepatic fibrosis staging in the two different Fuzheng Huayu preparations (Preps).
The serum and liver tissue biochemical examination revealed that both Fuzheng Huayu Prep I and II could obviously decrease serum ALT activity, total bilirubin level, increased serum Alb content, reduce hepatic collagen content, and improve SOD activity. It is indicated that Fuzheng Huayu Preps had good effects for treating experimental hepatic fibrosis. Compared to Fuzheng Huayu Prep II, Fuzheng Huayu Prep I had much better action on decreasing the collagen content and improving SOD activity.
